Most water heaters are only in service for 2-3 hours per day and they often have enough capacity to do extra work. If the BTU heating output of the water heater is equal to or greater than the heating load, you can probably use it to heat as well. Look at the label on the heater for the BTU output.

We have had good luck with the Polaris, but it does require competent installation. You should have a competent gas man do the work. This is not a good do it yourself project. Some people should have been given their money back instead of getting a new Polaris, because the problem is at the site.

A sulfurous or rotten egg-like odor in the hot water is caused by bacteria growing in the water heater. This usually happens when the water heater is turned off while on vacation, when the hot water has not been used for a long time, or when the temperature setting on the heater is set too low. The bacteria in the water heater are not a health threat; however, they must be eliminated to stop the odor problem. The procedure for eliminating the bacteria is called heat disinfection.

All solar water heating systems deliver both higher temperature water and more water volume than conventional water heaters. They heat typically 40 to 80 gallons more water than conventional water heaters.

We have provided a heater specially designed for iPool. It includes a heater, a filter pump (1000gal/hr), and connector. The heater is optional for iPool, the cost is $600 plus $60 shipping and handling fee. Please click iPool Heater for more information.

Only in areas subject to temperatures below 40 degrees for three or more days in a row. Water in the bio tanks should be kept at above 60º degrees F., 70º F. and above is ideal.

Yes. Since the water heater will operate far less frequently, solar will extend its life significantly.

It should be .There will be low heat output and high energy cost. They may be acceptable in intermittently occupied buildings or as a back up only. There will be a prompt payback of the added cost of any other form of energy.

Using what is called a desuperheater, GSHPs turn waste heat to the task of heating hot water. During the summer, when the system is in cooling mode, your hot water is produced free as a byproduct of the thermal process. In winter, with the heating mode, the desuperheater heats a portion of your hot water. Desuperheaters are standard on some units, optional on others. Stand-alone systems that will heat water all year around can be purchased.

It is impractical to use solar-generated electricity to heat water. A solar water heating system is a far more cost-effective choice. Similarly, space heating is best accomplished with solar thermal strategies or equipment designed for the task: passive solar designs and radiant heating, for example.

Testing by Florida Utility Companies and the State Energy Center reveal that heat recovery only saves about $39 to $69 a year - only 1/10 of the savings of solar energy systems. First, a heat recovery unit does not save any money when you are not heating or cooling. It saves the most money when you are air conditioning, because during this time the heat pump or air conditioner has free heat to expel.

Yes, but check with your local code enforcement department (some require boilers only) and make sure your water heater is sized correctly for the area you are heating. Set the water heater temperature control to high and make sure to install a thermostatic mixing valve and expansion tank.

There are many variables that dramatically affect heat loss, but here are some general guidelines, based on a new construction radiant slab, well insulated (walls, ceiling and under slab), in a moderately cold winter climate area using a thermostatic mixing valve: A standard 50 gallon electric water heater with (2) 4500 watts elements and a 20 gallon per hour (gph) recovery rate can usually heat about 250 sq ft.

In many cases an existing domestic water heater will do the job. If the BTU rating of the heater is matched with the BTU requirements of the space to be heated, one properly sized unit can provide both space heating and domestic hot water. A boiler is normally not necessary unless the heating requirements exceed 300,000 BTU's. In these cases, a simple mixing valve is designed into the boiler system to provide lower temperature water to the radiant floor.

We prefer not to install this kind of system. We feel it is an inferior product and potentially dangerous. We highly recommend using appliances without open flames (see #26 below) For the ultimate in heating and cooling, you must have separate systems.

Yes. Using what's called a desuperheater, some types of geothermal heat pumps can save you up to 75 percent on your water-heating bill by pre-heating tank water. Desuperheaters are standard on some units, optional on others. Some geothermal models can provide all of your hot water needs on demand at the same high efficiencies as the heating/cooling cycles.

You can take endless hot showers with the hot water the Titan provides. Because it does not use a tank, there is no limit, no hot water to run out of. You and your family can enjoy shower after shower without running out of hot water. And since the Titan heats water only as it is drawn, you will also save on your water heating costs. You will save AND have an endless supply of hot hater on demand.

Yes, but evidence indicates that smaller water systems such as those used in homes are not as likely to be infected with LDB as larger systems in workplaces and public buildings.

Note...While Kero-sun and Toyostove brand portable heaters are no longer sold in the United States, the following information relates to those units that were sold on prior years.

The way data bits are encoded into bits on the disk (the modulation system) was changed from EFM ("Eight to Fourteen Modulation", the Compact Disc's method) to the more efficient RLL1,7 (typical of hard drives).
